Warmed and humidified carbon dioxide for abdominal laparoscopic surgery: meta-analysis of the current literature
Résumé
The creation of a pneumoperitoneum for laparoscopic surgery is performed by the insufflation of carbon dioxide (CO2). The insufflated CO2 is generally at room temperature (20-25 °C) and dry (0-5 % relative humidity). However, these physical characteristics could lead to alterations of the peritoneal cavity, leading to operative and postoperative complications. Warming and humidifying the insufflated gas has been proposed to reduce the iatrogenic effects of laparoscopic surgery, such as pain, hypothermia and peritoneal alterations. Two medical devices are currently available for laparoscopic surgery with warm and humidified CO2.
